Just by judging from this one photo it´s hard to make any estimations
So just as a start and considering it stopped by the balance bridge I would suggest you take off the Winding mechanism and look at the backside of the swing weight. if it is getting caught in something like the screw holding the balance bridge you should see some scratches on the backside of it.
In general you should do something about the screwheads along the path the weight travels since they seem to have quite a loot metal shavings sticking up, just give them a quick polish so they are nice and flat othervice you might end up with small metal shavings inside the mechanism.

It's probably the placement of the weight you haven't got right. Could be tricky to get right. Haven't worked on a 1315 but have done the same on omega and tissot bumbers. The weight should rest halfway between the springs when not engaged in winding the movement up.

The pivot could be worn excessively causing the weight to droop, and catch on something. what happens when you hold the watch upside down? or one of the pawls in the ratcheting mechanism might not be releasing.

Hi All
I'm a beginner. I've finally competed my Seiko 6119A in a Seiko 5. I now notice that the second hand tube is quite long. It's not sliding down the shaft with moderate pressure. How had should I push? Is there a trick to this?
Thank you

Hello guys,
I have some problem with my seiko 7015 speedtimer that i bought 2 days ago..
This seiko runs smoothly when chronograph off
And when the chronograph is active,the watch runs for awhile and then stop..
Whats wrong with it and maybe you guys can help me with some solution please!!
thanks

Hi Len
thank you for the detailed reply. I tried a 329 today and unfortunately did not work. As you explained before it looks like the rotor is ocillating back and forth (the second hand moves forward and backwards).
Its heartbreaking to see as i was hoping to fix it and give back to my grandfather.
is there anyway i can source the part or an alternative movement (does not have to be Omega) that will fit the dial and casing?Although not ideal as takes away from the integrity and beauty of the watch but would love to able to get it working one way or the other so my grandfather can wear it on the wrist again.
any help would be much appreciated
regards

Another Swatch rescued from the junk pile. This one had a couple of obvious issues.

The leather band was filthy, heavily kinked, and stiff as a board. So much so that had to be scrubbed with detergent, dried, and some leather restoration work carried out.
The watch itself however, as well as the usual heavily scratched crystal had an electro-machanical issue. When I popped in a brand new battery, the second hand would move for a bit, then falter.
This turned out to be a combination of slight corrosion on the spring contact for the battery, and the fact that someone had previously run the watch with a tiny button cell, wedged in place with some scrunched up paper, which had bent the sprung battery contact. A little very careful re-bending and off it went like a champ.
This illustrates the point nicely, that even a little extra resistance in the battery contacts can be enough to stop a quartz movement, or make it behave erratically.
The band took a little more effort. Once dried, following its bath, it became obvious that the original uniform kid leather look was long gone, so I went for a more vintage finish, with a little blending of the very worn patches using the leather dye in some dark tan shoe polish, combined with some lighter "Clarks Shoes" branded leather restoration cream.
I only needed a hint of the dark tan, since I didn't want to end up with a brown shoes effect, simply to shine up the worn patches, and blend them with the existing colour.

Several thin coats of leather cream mixed with a little dark tan, and much buffing later and the strap is back to its original soft calfskin feel, rather than dry as a stick. All of the holes are the same size again.
The band forms a gentle curve, rather than being corrugated, and the stitching is clean. The band looks ten times better than when it arrived. This is yet another member of the "404 Club", since it was effectively free with a bunch of other junk, I picked up which was purchased because it included a mechanical watch that I have yet to restore, all for under the magic £4.04
